REGULATlNGi-VALVE FOR GAS-BURNERS.

Specification of Letters Patent.

Izatented April 16, 1907.

Application iiled June 8,1906. `Serial No. 320,776.

Be it known that I, FREDERICK Econ, av citizen of the United States, residing at Bridgeport, in the county of Fairlield and State of Connecticut, have invented certain new and useful Improvements in Regulating- Valves for Gas-Burners and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

illy invention relates to regulating-valves for gas-burners, and consists of certain parts and arrangements of parts such as will be hereinafter fully explained and then particularly pointed out in the claim which concludes this application.

The object of my invention is to automatically prevent the accidental escape of gas from the burner.

In the accompanying drawings, which form a part of this application, Figure l is a vertical sectional elevation illustrating my improvement with the parts in normal position; Fig. 2, a similar view showing the position of the parts with the gas-pressure on and immediately after certain mechanical appliances have' been operated to allow the escape of gas through the burner, and Fig. 3 a section taken at the line 3 3 of Fig. 1.

Similar numbers of reference denote like parts in the several 'ligures ofthe drawings.

l is the 'base-section of the burner interiorly threaded at the bottom for attachment to a gas-fixture, the upper portion of this section terminating in a reduced nipple 2, which is threaded eXteriorly. 8 is a valveseat formed in the upper portion of this nipple, and a small duct leading from the interior of the section l into said seat. 5 is a ball-valve which by gravity normally rests within this seat so as to out oil the escape of gas.

6 is an intermediate sectionhollow throughout its length and having a reduced exteriorly-threaded upper portion, to which latter the gas-burner 7 proper is screwed, while the lower portion of this section is interiorly threaded and screwed on the nipple 2.

Pivoted at S between ears a a, projecting upwardly from the top of the nipple 2, is a gravity-dog 9 which normally swings into osition immediately above and against the all-valve 5, so as to lock the latter as against any upward movement, as shown at llig. 1, one of the lower corners of said dog being beveled or rounded, as Vshown at l0, for the purposes presently to be explained.

Il is a small tube screwed within the side of the section 6 l2, a small plunger-pin eX- tended through this tube within said section; 13, a coil-spring within this tube and around the pin, and 14 a small head secured to the outer end of the pin. This pin is horizontally disposed, and its normal position is in a direct line with the lower portion of the dog 9.

Presupposing the parts to be in the position shown at Ifig. l, the operation of my improvement is as follows: The pin is thrust inwardly against the dog, thereby swinging the latter to one side, and thus permitting the pressure of the gas to elevate the ballvalve against the lower beveled corner 10 of the dog, as shown at Fig. 2, whereby the pressure of the gas will keep the parts in this position and the gas can then readily escape up through the burner. When the pressure of gas goes down, the ball will rest upon the valve-seat,.and the dog will swing into nory mal position above the ball, thus locking the latter in place. The provision of the small bevel l() on one of the lower corners of this dog permits the ball to rise without getting out of contact with the dog. If this dog had a sharp corner instead of a bevel, the ball could not rise until it could clear the dog entirely, and this would be apt to seriously interfere with the successful operation of my improvement, because the return swing of the dog would be apt to cause the latter to impinge against the ball with sufficient force to prevent the latter from dropping backl into its seat; but although I consider this bevel to be necessary in instances where I am obliged to use a very light ball made of aluminium on account of a light gas-pressure, still I do not desire to be limited thereby, since in the instance of a heavy ball and a greater gas-pressure such bevel might be done away with. Also the middle section 6 and the gas-burner proper may be made in a single piece, if desired, although for the purposes of convenient assembly I prefer the construction illustrated.

While I consider the loose ball-valve as a very simple and effective construction, it will of course Abe obvious that the shape of the valve is immaterial, so long as said valve is capable of a free operation by gravity.

The plunger-pin which I have shown and described or some similar mechanical device is, as a rule, necessary, although a light tap IOO IIO

against the side of the burner so as to cause a su'Hieient vibration will effect the displacement of the dog, and thus allow the pressure of gas to elevate the valve.

Having thus described my invention, what I olaini as new, and desire to'seeure by Letters Patent, is-

A regulating-valve for gas-burners, oomprising a base-section provided with a single central gas-duct, a reduced, threaded nip ple at the upper end of said section, a valve-seat overlying said gas-duct and being formed below the top of said nipple, a pair of ears FREDERICK EGGE.
